' of the same, -reference being had. to the accompanying drawings, making a nartof my speci-` iication, in which- Figure 1 represents a trausverse'vertical section of myinvention. Fig. 2 isa sidev eleva- .tion of the same. Fig..3 showsa section of the shoe-rail when rolled.,

Similar letters of reference'in the views in- -dicate corresponding parts.

This invention consists in forming the pile of several fiat bars of iron, two of which are about of equal width and placed in such a relativev position to each `other that they form an inverted T, the stein or vertical part oi' which is kept in position .by two'or'niore dat bars that are placed one or more on each side of said vertical part and on the top of the base, and the width of which is equal to one-half the width of the base-less one-half the thickness of the vertical bar, the whole being arranged and combined n'such a manner that ordinary bars vof iron-such as are usually made and sold inthe market-can be used for forming the pile without subjecting them to a preliminary rolling or other operation, and that by passing the pile lonce through suitable rollers nished shoe-rails are produced.4

To enable others skillediin the' art toxnake and use my invention, I will proceed to de#l scribe it` with refrenceto the drawings.

My pile is formedof aseries of dat bars, A B C C', which arearranged in relation to each other as clearly shown in Fig. 1 of the drawings. The barA, which forms the base of the pile, is fully as widel as the base of the intended shoe-rail is to be, and of any convenient thickition-or end view of the two bars is similar to.

an inverted T. This ba;l is intended to form the vertical part or tread of the shoe-rail, `and its thickness is about equal to the thicknessfof the tread to be formed, While its height o'r width exceeds that of said tread, as'will be `clearly understood by comparingFigs and 3 of the drawings. a 'd Bars C C are placed on th'e top of the barv Aand on opposite sides of 'bar B, so that they steady the same in its position.- The width of these bars is equal to one-half the width of the bar A less onelhalftthe thickness of the bar B, and they,- together with the bar A, form the base of the intended rail. The thickness o. the bars C C therefore is so selected that the same, together with bar A, contain sucient iron to make upl thebase of the rail, and, if

it should be desirable, two'orv more such bars might be placed,one on the top of the other, on

either side of thev bar B. Thus arranged, the

pile is heated and passed through suitable rollers, and the shoe-rail is formed and finished in one operation.- 1 I .I

Itwill be -noticed that the bars which I use for my pile can be selected from such iron as .is generally rolled vout and sold in the market,` so that no extra.A rolling is required info rder to t them'for the pile.

Having thus fully described my'1invention,

what I claim as new, and desirelto' secure by .Letters Patent, *is* v Themanner herein shown 'and-'described of arranging or disposing the* bars A B C C in forming a pile, for thepurpose set forth.
